Optical Fiber Identifier Test Tool 1310-1550nm Detector High Performance Description: - Add a 1310 or 1550 nm source (frequency 270, 1k or 2Khz) to the upper end of a large number of fibers. - Then, at the other end, the optical fiber identifier is used to test all the fibers in turn. If a power, direction or frequency indication is found, the fiber is the fiber to be sought. - The fiber identification device can match the fiber: 3mm or 2mm (fiber jumper), 0.9mm fiber jumper cable (tight sheath fiber), 0.25mm bare fiber (removed bare fiber) - Can identify 3 commonly used signal frequencies, ie 2KHz, 1KHz, 270Hz - Digital display of relative optical power in fiber - Distinguish the direction and frequency of light without interrupting the fiber - Easy to operate and convenient with one-touch operation - Provide corresponding adapter heads for bare fiber and various pigtails Package Includes: 1Pcs Optical Fiber Identifier 1Pcs Accessory About : All items will be within 3 business after the payment is received.
